S125 Rugged IP68 350Bar Waterproof Submersible Stand Alone Linear Position Sensor.


Position feedback for marine and offshore applications
Available in any travel from 5mm to 800mm.


The S125 LIPS® (Linear Inductive Position Sensor) is a higher pressure version of the S115 sensor with a larger electronics housing and wet mate high pressure connector. The S125 is sealed for continual submersion up to 3500m (350bar 5000psi). The unit is compact, space-efficient and responsive along almost its entire length.
Like all Positek sensors, the S125 provides a linear output proportional to displacement. Each sensor is supplied with the output calibrated to the travel required by the customer, our standard range covers any measurement range from 5mm to 800mm. As with all of our packaged sensors full EMC protection is built in.
The sensor is very robust, the body and push rod being made of 316 stainless steel for long service life and environmental resistance.
Overall performance, repeatability and stability are outstanding over a wide temperature range. The sensor is easy to install with mounting options including 316 stainless steel M8 rod eye bearings and 316 stainless body clamps. The push rod can be supplied free or captive, with female M8 thread, or an M8 stainless steel rod eye. The S125 also offers a wide range of mechanical and electrical options, environmental sealing is to IP68 350Bar (5000psi).
This sensor is waterproof for submersion to 3500 meters.

Preferences

Positek offers a range of options for its standard sensors.
Each sensor is manufactured to suit each customer's preferences.
If your requirement is outside the options given below,
Positek can modify/ redesign a sensor to suit your specific requirement.
Standard options are available as below:

 

Measurement range:

Factory set to any length from 5mm to 800mm in increments of 1mm.
For example, if your application requires 10" (254 mm) measurement
then Positek will manufacture the sensor specifically for this length.
The mechanical length and calibration will be set up for 254 mm.
